The Water Environment Federation (WEF; Alexandria, Va.) Students and Young Professionals Committee completed its fourth annual community service project Oct. 15 during WEFTEC® in Los Angeles. Nearly 90 volunteers participated, planting 37 trees at South Los Angeles Wetlands Park. The wetland is designed to capture and filter stormwater runoff before it enters the Los Angeles River, and volunteers created a stormwater irrigation system for the trees using infiltration piping.
